Question

two terms is having same difference.first term of one of these is 3,then that of other is 8.what is the common difference between their 2nd terms,4th term,10th term and 30th term.

Answer 1

Hii friend,

first term(a1) = 3

Second term (a2) = 8

Common difference (D) = a2-a1 = 8-3 = 5 .

First term = a = 3

Second term = a+d = 3+5 = 8.

Fourth term = a+3d = 3+3×5 = 3+8 = 11.

Difference between fourth term and first term = 11-3 = 8.

Tenth term = a+9d = 3+9×5 = 3+45 = 48.

Difference between 10th term and first term = 48-3 = 45.

HOPE IT WILL HELP YOU WILL..... :-)
